Electromagnetic Rollercoaster Grades 9-12

Governed by IEEE & IEEE-HKN

Using copper wire, cardboard, tape, magnets, and a battery, those competing will create a circular coil that follows along a rollercoaster path made out of cardboard. The video below can be seen as a reference on how to create the coil: https://youtu.be/Fd3O6sXBXqA?si=D4GApRQ9quT2Y1pd

This video is an example roller coaster that has been made before: https://youtu.be/Wm3JOlJ8oKc?si=piXrwZeMXZs577iY

Anything may be used to create the circular form for the coil, as long as it does not remain during testing. The objective of this competition is to have the longest lasting rollercoaster system. Longest lasting as in your time will still be counted until the battery comes to a complete stop.


There are very few rules on how to compete, which will be stated in simple details here:

  1. When competing, the only materials should be copper, cardboard, tape, magnets connected to the battery, and the AA battery.
  2. Anything may be used to create the coil form for the copper
  3. The rollercoaster must have at least one inclined surface, to ensure that it is not just a circle.
  4. The rollercoaster capable of lasting the longest time will win.
